A slicing approach to stress-strain duality
Virginia De Cicco, Giovanni Scilla
The classical Kohn-Temam stress-strain pairing for symmetric tensors and is typically formulated under summability assumptions on the…
Gauss-Green formulas for divergence measure tensor fields on rough domains
Virginia De Cicco, Giovanni Scilla
We introduce a notion of pairing between essentially bounded tensor fields with divergence measure and vector-valued functions of bounded variation, extending the classical theory…
Beyond : new pairings and Gauss-Green formulas for measure fields with divergence measure
Giovanni Eugenio Comi, Virginia De Cicco, Giovanni Scilla
A new notion of pairing between measure vector fields with divergence measure and scalar functions, which are not required to be weakly differentiable, is introduced. In particular…
Relaxation of nonlinear elastic energies related to Orlicz-Sobolev nematic elastomers
Giovanni Scilla, Bianca Stroffolini
We compute the relaxation of the total energy related to a variational model for nematic elastomers, involving a nonlinear elastic mechanical energy depending on the orientation of…
